If Wales played their "third team" against England then they are obviously morons. Playing that team does **** all to get the 1st team ready for the world cup. Either that, or the team that lost to England is the world cup team. Either way, your ****ed.
If the Welsh coach played "regional tactics" against England, then Wales are ****ed. This means he is either "experimenting" which is pretty moronic so close to the actual competition, as you should be refining tactics by now. Either that, or those are the tactics he is going to use in the RWC.
With all that said, England aren't exactly in great form, and have been pretty much piss poor since they won the competition. Scotland never acheive anything in internation sport, unless drinking butter is now a sport. Irel;and have a good team, but probably not good enough.
Also, this years RWC is in France and starts on September 7th, I expect fans will begin arriving about a week before hand, so you can bet your ass France will have surrendered to everyone by September 1st.
